Multi-functional abrasive dust machine

Technical field

The present invention relates to abrasive dust equipment, the multi-functional abrasive dust machine of particularly a kind of pendulum-type.

Background technology

Existing pendulum type ring roll pulverizer is that central shaft is installed on the pedestal of center with bearing, and the central shaft upper end is connected with the plum blossom frame, and Burnisher apparatus is distributed in around the plum blossom frame.Relieving tool post top is contained on the plum blossom frame, and matches through bearing and pedestal top, center, and following of lower end and relieving tool post link, and following of relieving tool post is formed labyrinth sealing between the pedestal of center down, prevents that dust from getting into bearing.The perching knife parts are distributed on the relieving tool post lower bottom base, and its effect is abrasive material to be shoveled between bull ring, the grinding roller grind.The center pedestal is contained in the base bottom, and the cover wound packages is surrounded by steam return box around the base above base, and its effect is to grind the distinguished and admirable importing that air blast comes indoor.The base right part has ventilating duct, and air channel and bottom all are equipped with the liner plate back of being convenient to wear and tear and are changed.Bull ring is pressed in the base holes with bolt.The cover tube is installed on the base.Burnisher apparatus is made up of grinding roller axle, grinding roller, seal receptacle, gland, skeleton rubber oil sealing, clamp nut, bearing, grinding roller cover, horizontal axis tam, sleeve, axle sleeve etc.

The flour mill of this structure, because the height of Burnisher apparatus is higher, vibrations are big during use, operation stability is relatively poor; Weight is big, required drive is bigger when rotating, and energy consumption is higher; Burnisher apparatus oiling maintenance, repair inconvenience.

Summary of the invention

The objective of the invention is the deficiency to prior art, and provide a kind of simple in structure, cost is low, energy consumption is little, stable, maintenance and multi-functional abrasive dust machine easy to maintenance.

The objective of the invention is to realize through following technical scheme:

A kind of multi-functional abrasive dust machine comprises central shaft, grinding roller, bull ring and perching knife, and bull ring is arranged in the base; Central shaft is arranged on the central shaft bearing block through taper roll bearing; The central shaft bearing block is arranged on the bottom of base, and central shaft is connected with power set, and different with prior art is: also comprise the grinding roller frame; The Center-to-Center axle of said grinding roller frame installs, and the equal five equilibrium of each grinding roller is rotatable to be arranged on the side of grinding roller frame.

Described grinding roller frame is circular or polygonal star.

Further, described grinding roller frame be triangle star ~ anistree star any.

Further, described grinding roller frame is triangle star or anistree star.

The side of said grinding roller frame is provided with the grinding roller groove.

Described grinding roller is the cydariform or the cylinder bodily form, and its center is provided with the axis hole greater than grinding roller axle external diameter.

Described bull ring is taper shape or annular.

The interior circle of said bull ring is provided with deep-slotted chip breaker.

During work, power set drive the central shaft rotation and make the rotation of grinding roller frame, and the grinding roller that is arranged in the grinding roller groove is also followed around the central shaft rotation; Grinding roller receives action of centrifugal force; Impact to the bull ring inwall, the relieving tool post that is contained in below the grinding roller frame also and then rotates around central shaft with perching knife, and perching knife scoops up the abrasive material on the base; Deliver between grinding roller, the bull ring; Owing to receive function of friction between grinding roller and the abrasive material, grinding roller is around the rotation of grinding roller axle, and abrasive material is rolled between grinding roller and bull ring becomes powdery.

The grinding roller of this flour mill is set directly in the grinding roller frame, saved baroque Burnisher apparatus in the former complete machine, thereby complete machine structure is simple, has saved the cost of complete machine; Be applicable to also simultaneously that the cost of transformation is lower to the transformation of existing flour mill; Maintenance and maintenance have in use been saved to Burnisher apparatus; Complete machine weight saving, the power that needs during work reduces, and has reduced energy consumption, has reduced production cost; The grinding roller frame is arranged in the base, has reduced the height of equipment, and vibration is little during work, operation stability is high.
